Constant ADSL dropouts since 3-4 days ago, Epping NSW

Dear TPG,I have been a happy TPG customer for more than 10 years, with 5 years in the current address.Lately though I'm getting constant ADSL Line dropouts since the past 3-4 days, day and night.My ADSL2+ line was working perfectly fine until last week. I thought it might be a temporary issue but it is continuing for too long.I tried 2 different ADSL2 modems and brand new filters, but the same result.

Line will sync for a few minutes and authenticate successfully with PPPoE then after a while the system log shows PPP error. It tries to sync again, authenticate, establish connection, then another PPP error again. Complaining about LCP?I can see my user ID and password works in the log, line sync speed pretty good, then PPP error comes up.My street just got NBN enabled last week. Is that affecting my ADSL, too much of a coincidence to ignore?I'd appreciate it if you could check the PPP authentication of my account dxxxxxxxx, and fix the cause of why PPP session is frequently invalidated please.Both modems are TP-LINK ADSL2+ variants.

Would really appreciate your help as holidays without the internet would be very inconvenient!

I ran initial tests on your connection and it shows a High capacitance load on the line. Does your modem connect to a filter-splitter together with a home phone? Also, how many wall sockets do you have?

I recommend to isolate the modem alone on the wall socket and see if the dropout will still occur, else try to isolate the modem to a different wall socket.

Let me know once it is done and I will run additional tests; in case the dropouts will still persist I may need to arrange one of our Technicians to call you for further tests.

I live in a unit with just one wall socket for telephone, and yes I have been using a filter spliter. Just to eliminate the possibility of filter failure I used a brand new filter too, when the problems first occurred.

For now only the modem-router is connected to the wall. Could you please run your test again to see if anything has changed after the change on my side?

Thanks for getting back with additional details. Your connection still shows multiple dropouts on the line. I'd like to arrange one of our Technicians to call you tomorrow for further test and investigation.
